Can confirm the Magneto problem (Xtreme doesn't return to normal playing time). However, I did only encounter it one in 10+ tries. Seemt to be something very random.
On good news: Nightys Xtreme seems to be fixes now.
But I have a problem with Hulk. Half his moves don't work properly anymore. Had a quick look and one of his files in the actors folder is only 1/3rd in size or so, and that is where the problem originates
PS: Why are there so many fightstyles of characters actuall in MUA in the package?
